It is important in airplane structure design to make a structure that strong enough and as light as possible. A lightweight structure is not only beneficial for the structure aspect but also other aspects like aerodynamic and cost. Optimization is needed since preliminary design to make an efficient configuration of structure as light as possible while satisfying safety requirements. Composite material has a high strength-to-weight ratio. It means the structure can be lighter but still strong enough. It is very beneficial for the airplane design process. This paper conducted optimization of composite structure wing with laminae thicknesses as design variables and structure weight as objective using Gradient- Based method by MSC Nastran. The constraints for this optimization are the Tsai-Hill criterion and buckling factor to determine whether the structure safe from static load and buckling phenomena or not. Optimization results had shown that the most critical constraint is the buckling factor, this result has the heavier weight. Then, further analysis of static load was conducted to ensure the last configuration is safe from both constraints. [ABSTRACT FROM AUTHOR] |
